• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty xang xa hoi. hieu ((ve cac) or (vien da)) xuc ban ((hang ve) OR (hang ke)) cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty xang xa hoi. hieu ((ve cac) OR (vien da)) xuc ban ((hang ve) OR (hang ke)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty xang xa hoi. hieu ((ve cac) or (vien da)) xuc ban ((hang ve) OR (hang ke)) cua tu".
• Adding a wildcard symbol may retrieve word variants: thu sach ty xang xa hoi. hieu ((ve cac) or (vien da)) xuc ban ((hang ve) OR (hang ke)) cua tu*.
